To all whom it may concern:

Be it known that l, GEORGE G. GLENN, a citizen of the United States,residing at Gastonia, in the countyof Gaston and State of NorthCarolina, have invented a new and useful Improvement in Machines forReshaping Bottle-Caps, of which the following is a specication.

The object of my invention is to provide a simple and practical machinefor repairing previousl; used metal caps for bottles by reem and at thesame time inserting new cork disks therein, and it consists in the novelconstruction and arrangement of the machine, which I will now proceed todescribe with reference to the drawings, in which Figure 1 is a verticalcentral section with the pedestal and magazine broken away. Fig. 1a isan enlarged sectional view of the lower art of the pedestal taken atright angles to ig. 1. Fig. 2 is an enlarged perspective view of theupper portion of the machine. Fig. 3 is a horlzontal section on line 8-3of Fig. 1. Fig. 3a is the same view as Fig. 3,

vbut showing a different position of parts.

Fig. 4 is an enlarged sectional detail on line 4-4 of Fig'. 3a. Fig. 5is an enlarged sectional detail on line 5-5 of Fig. 1. Fig. 6 is anenlarged sectional detail on line 6-6 of Fi 3 and Figs. 7, 8 and 9 aresectional detas of various forms of dies.

In the drawing, Fig. 1, X is a hollow column having a spreading hase Xand a spreading top X2 forming a pedestal frame on top of which isbolted a bed A recessed in the middle and having a raised outer edge.

G is a treadle normally held up by spring, H and arranged to pull down arod E an having a stop screw F for limiting the rise of the' treadle.The pull rod E is attached to a vertically reciprocating plunger stem Cslid- 'ing in a sleeve B of a turn-table B. The

turn-table rotates on the raised edges of the bed A and this bed has astationary en'dent sleeve A2 in which rotates the sleeve of theturn-table. This long bearing is tol secure accuracy in the movingparts. The turny table B has in lts upper face a series of die 50 seatsi7, which receive the metal bottle caps to be re-shaped and on the upperend of the stem C is mounted a cross head D which at its opposite endson the under side carries -two dies and y adapted to enter the die seatswhen the head is brought down by the treadle. One of these dies :tre-shapes the second-hand bottle caps, and the other one 'y forces intothe re-shaped cap one of the cork disks z taken from a vertical magazineI by a recjiprocating feeder bar R having forked end fr, 1g. 3. c

Referring now to Fig. 2, the plunger head D is connected by a link Jwith the arm K of an elbow lever fulcrumed at 7c to a stationarystandard and having its other arm K descending to and grasping in itsfork a later' ally projecting pin L. This pin'is attached to ahorizontal reciprocating bar M, Fig. 3, sliding in the part A of thebed. On the rear end of the bar M is fulcrumed at m a short lever N, oneend Q of which is formed as a mutilated gear engaging teeth t on thecork disk feeder R and the other end of which is slotted at O to receivea pin P mounted on-to of slide M.

The inner en m2 of the bar M, sce Fi s. 1 and 3a, is formed into alocking detent w ich enters one of a series of notches d, Fig. 2, in theedge of the turn-table, which are spaced a distance apart correspondingto the space between the die seats, so as to stop the turntable withtwo'of its Adie seats immediately b'elow the dies :t and y of theplunger head. The bar M is advanced to the locking position when the luner rises. When the plner descends t e el ow lever K K forces the ar Mback.I This latter movement causes slide'M and pin P to force back theconnected end of lever N, while the'toothed end Q is moved forwardlywith the disk feeder R and the forked end r of the disk feeder, which isa little less than the thickness of the disk, and forces a cork disk outof the magazine and directly over the die seat below the die y, as seenin dotted lines at z in Fig. 1. Then when the plunger and head comedown, the die 'y forcesthe cork disk into the bottle cap which isresting in the die seat. When the disk feeder is thus advanced it muststop for a moment, while the die is going to its lowest point, and forthis purpose the slot O in lever N is made with an angular bend, so thatwhencork feeder R has been advanced to feed a cork, as in Fig. 3, theouter angular end of the slot O is thrown intothe longitudinal alinementof the travel of pin P and the latter is free to move outwardly in thesame, as indicated by the dotted lines in Fig. 3". without moving thecork feeder R. During this stationary interval of cork feeder R the:dies -fj/ complete ytheir descent to force the cork into one cap andswage the other.

After the downward 4movement of the'dies is completed and they start torise, see Fig. 2, elbow lever K K is rocked in the reverse direction anda hooked spring paWl C2 mounted on a post p on bar M is forced by springu into a ratchet wheel B2 on top of the turntable ,and as the pawladvances it turns the ratchet wheel and turn-table the space of one dieseat, the end 'm2 of the barM at the last part of the movement enteringone of the notches d in the turn-table and fixing its position for thenext descent of the plunger. When the cap has had the cork thus placedin it,-the cap with its cork is lifted out and discharged as follows. Onthe top of the bed A is a small cam e, shown in curved d otted lines inFig. 3a, and in sectional detail in Fig. 6. In each die seat there is asmall lunger b and as the turn-table carries this p unger over the came'the latter forces up the plunger and lifts the cap above the surfaceof the turntable, and as the latter turns further a sta` tionary scraperarm s sweeps off ,the cap from the table into any suitable receptacle.

The dies a," for re-shaping may be made in various shapes, but they allhave a spring seated push-olf center for discharging the cap and keepingit from hanging on the swaging'die. This push-off centermay be made asin Fig. 7 with a headed plunger having spiral spring w3 above it, or itmay be as in Fig. 8, with a plunger w having a spiral spring above itand a retaining pin and slot, or it may be made as in Fig. 9 with alarger luiiger :c4 and a spiral spring :1:5 entering a c arnber in thesame and having two retaining pins and slots.

As the cross head D moves up and down it is guided and steadied foraccurate registration with the subjacent die seats, and for thispurpose, see Figs. l and 5, a small fin or rib f is formed on the endofthe cross head and this is received intoa vertical slot or vchannel inthe magazine I.

As the cork disks are very light it is necessary to secure a morepositive downward feed than is furnished by their own gravity. For thispurpose I employ a superposed weight 'w on top tof the stack of disks asseen in Fig. l. This overcomes any tendency of the disks to hang fromfriction in the magazine and thus positively and accurately brings thebottom disk into the plane of action of its reciprocating feed bal R.

The operation of re-shapin'g the caps is as follows: The old caps arefed into the die seats just to the right of the stripperbar s, seen inFig.- 2. The next movement of the turn-table brings a cap under theswaging die m. After all the die seats around to the cork magazine havebecome thus filled with swaged or re-shaped caps, the next movement ofthe turn-table brings one of these re-shaped ca s under the die y and acork disk is force out by feeder R and is pressed scacco down by the diey into one crown ca at the same time that die re-shapes anot er cap onthe. opposite side. Then as the table turns again the dislodging plungerb rides up on the cam e and lifts the cap up so that it may be swept offby the stripper s. It is important that the swaging die a: should be soformed that it will not mutilate or destroy the little knob points ofwhich there is in the bottle cap a circular series for subsequentfastening on to the bottle neck. I use for this purpose a smooth plungerdie that does not destroy the knob points, instead of a fluted die, asthe iiuted die could not be used because the knob points are not ofuniform size, and my smooth die is so shaped that the swaging is done,as stated, so as not to mutilate or destroy the knob points.

An important feature of my invention consists in mounting the swagingdie and the corkinserting plunger on the cross head on opposite sidesofthe vertical reciprocating stem, so that both enter the seats in thesubjacent turntable at the same time for double action. This not onlybalances the strain on the cross head, but the die and the plunger c0'operate reciprocally,'each helping the other to insure its accurateregistration with the seats in the subjacent turn table; that is to say,the penetration of the swaging die into its seat insures theregistration ofthe plunger with its diametrically opposite seat.Furthermore this arrangement gives a proper interval of space on theturn-table for ap-V plying and removing the caps between the twooperations and as two o erations are performed at each descent of t ecross-head the el'liciency of the machine is increased.

Althou h I have shown my machine as operated y a treadle, I would haveit understood that it is also designed to be run by a lpower appliancethrough a belt, or 1t may driven by a motor connected to the machine.
